Real Survival

Real Survival mode, known in Japan as the "Real Survival Mode" (リアル・サバイバル・モード,Riaru sabaibaru mōdo?), is a feature in the 2002 remake of Resident Evil and its HD remaster. It is unlocked after completing "Once Again...", which is itself unlocked after completing the game once, saving it, and starting a new game from a Cleared Save file. In this mode, the game is set to Hard difficulty, auto-aim does not work, and the item boxes are no longer interconnected.

This mode is a reference to prototype versions of the original 1996 game: originally, the item boxes were not intended to be interconnected with one another, but this was changed later in development due to criticism from testers.

The doorknob that usually breaks after opening the door twice from the East staircase through to the corridor to the back entrance will no longer break in Real Survival mode;[1][2][3] this is acknowledged in the message that either Barry or Wesker leaves for Jill or Chris in the courtyard, respectively, where they now do not mention that they have fixed the doorknob.
